}

上面是事務管理的配置，而後在我一個service.impl類中進行了一條正確的插入，一條錯誤的插入，發現每次都會往數據庫中插入數據，明明報錯了就是不回滾。

public boolean saveRole(Role role) throws Exception{
		// TODO Auto-generated method stub
		roleMapper.saveRole(role);
		return roleMapper.saveRole(role);
	}

因爲編碼是唯一鍵，重複插入會報錯。剛剛開始以爲是tx切面沒有切到，後來搜索了一下才發現是shiro在啓動配置的時候Spring還沒啓動。

解決辦法：

新建一個spring的監聽來設置realm。

import org.apache.shiro.realm.AuthorizingRealm;
import org.apache.shiro.web.mgt.DefaultWebSecurityManager;
import org.springframework.context.ApplicationContext;
import org.springframework.context.event.ContextRefreshedEvent;
import org.springframework.context.event.EventListener;
import org.springframework.stereotype.Component;

/**
 * spring初始化完成後設置自己的realm
 * @author 胡漢三

 */
@Component
public class SpringEventListener {
    @EventListener
    public void handleContextRefresh(ContextRefreshedEvent event) {
        ApplicationContext context = event.getApplicationContext();
        DefaultWebSecurityManager manager = (DefaultWebSecurityManager) context.getBean("securityManager");
        AuthorizingRealm realm = (AuthorizingRealm) context.getBean("authRealm");
        realm.setCredentialsMatcher(new CredentialsMatcher());
        manager.setRealm(realm);
    }
}

並且一定要註釋掉原來shiro配置裏面的realm：

@Bean(name="securityManager")
	public SecurityManager securityManager() {
		System.err.println("--------------shiro已經加載----------------");
		DefaultWebSecurityManager manager=new DefaultWebSecurityManager();
		//manager.setRealm(authRealm);
		// 自定義緩存實現 使用redis
		manager.setCacheManager(cacheManager());
		// 自定義session管理 使用redis
		manager.setSessionManager(SessionManager());
		//記住我
		manager.setRememberMeManager(rememberMeManager());
		return manager;
	}

一定要註釋shiro配置類中securityManager裏面的manager.setRealm。這樣事務就正常了！當然數據庫要注意一些數據庫引擎是否支持事務！
